Raisman, one of the members of the U.S. "Fierce Five" gymnastics team at last summer's London Olympics, has been given odds of 5 to 1 to win, Las Vegas oddsmaker Johnny Avello told ABC News.

"She's just 115 pounds of energy. And if she follows someone like Shawn Johnson, who knows? Maybe she can win it all." Avello told ABC News radio. "Now, it is early, but I think she'll be a contender."

Johnson is a former "Dancing with the Stars" champion, and inspiration for Raisman.

Annie Barrett, a longtime Dancing with the Stars recapper for Entertainment Weekly, told ABC News Raisman is the contestant to beat.

Athletes including football players, a gymnast and a speed skater have dominated past competitions, winning six of the past 15 seasons and placing second five times.

Barrett said that recent Super Bowl winner Jacoby Jones of the Baltimore Ravens is a wild card in the competition and could use his charm to his advantage. If Jones has the footwork like fellow NFL players Emmitt Smith and Donald Driver, who each took home the Mirror Ball trophy, he could come out a winner.

A maid who cleaned the home of former New England Patriots player Aaron Hernandez has testified at his murder trial that she saw him "messing with" the security camera in his basement the day after the killing.
